Pectoral girdle and upper limb Flashcards
What is the term for ‘forearm’
Antebrachium
What is the pectoral girdle made up of?
Clavicle
Scapula
What is the upper limb made up of?
Humerus
Ulna, Radius
Carpal, Metacarpal
Phalanges
What is the joint name and type between the sternum and the clavicle?
Sternoclavicular joint: synovial, modified gliding (has certain ball and socket/saddle properties)
What is the joint name and type between the clavicle and the scapula?
Acromioclavicular joint: synovial, gliding
What is the joint name and type between the scapula and the humerus?
Glenohumeral joint: synovial, ball and socket
Where is the coracoid process?
posterior process, looks like a crow’s beak
What is the groove above the spine of the scapula?
supraspinous fossa
What is the groove below the spine of the scapula?
infraspinous fossa
Where is the subcapular fossa?
under the coracoid process
Which part of the scapula and the humerus make up the glenohumeral joint?
Glenoid cavity of the supraglenoid tubercle of the scapula
Head of the humerus.
Which ligaments holds the glenohumeral joint in place?
Superior glenohumeral joint
Middle glenohumeral joint
Inferior glenohumeral joint
What tendon holds the long head of the bicep in the intertubecular groove?
Transverse ligament
What are the movements facilitated by the transverse ligament
Flexion-extension
Abduction-adduction
Rotation
What is the glenoid labrum and what is its main purpose?
The glenoid labrum is a fibrocartilaginous tissue on the rim of the glenoid cavity, it deepens the cavity, allowing the head of the humerus to be more stable.
What is the movement facilitated by the glenohumeral joint?
Sliding and gliding
What are the 5 features of the proximal end of the humerous?
- Head
- Anatomical neck + Surgical neck
- Greater Tubercle
- Lesser Tubercle
- Intertubecular groove
What are the 2 features of the body of the humerus?
- Shaft
- Deltoid tuberocity
Name the 3 fossae on the distal end of the humerus
- Coronoid fossa
- radial fossa
- Olecranon fossa
Name the 2 epicondyles of the distal humerus
Lateral and medial epicondyle
Name the 2 condyles of the distal humerus
Trochlea and Capitulum
Which condyles of the humerus forms the joint with the radius and ulna?
Capitulum -> Radius
Trochlea -> Ulnar
Describe the 3 parts of the humeroulnar (humeroradial) complex
- Medial collateral ligament (3 parts)
- Annular ligament (medial)
- Lateral collateral ligament
How does the antebrachium go from supination to pronation?
Synovial pivot of the proximal radioulnar joint, the radius rotates on top of the ulnar.
